NEW ORLEANS (AP) - Beyonce answered critics of her Inauguration Day performance the best way she could - with another sterling performance of the national anthem.

The difference?

On Thursday, it was live: She admitted during her Super Bowl news conference that when she performed for President Barack Obama and the nation, she decided to sing to a prerecorded track because she didn't have time to practice.

Calling herself a self-proclaimed "perfectionist," she said wanted the day to go off without a hitch.

Then, she sang it once again, sans accompaniment.
